To do some very preliminary budgeting for purchasing an older single
engine aircraft, I need an idea of how long of a term that a finance
company might provide for a 30 year old aircraft. I suspect there must
be a typical limit for aircraft over a certain age.

Does anyone have information that can get me in the ball park?
Is it possible to get a 15 year or even a 20 year loan on a 30 yo
plane?
